Don't run compilation in Post run

[kenorb]

Example:

async function run(): Promise<void> {
  try {
    const sourceSettings = await inputHelper.getInputs()

    try {
      await foo();
    } finally {
      await foo();
    }
  } catch (error) {
    core.setFailed(`${(error as any)?.message ?? error}`)
  }
}

async function cleanup(): Promise<void> {
  try {
    await foo();
  } catch (error) {
    core.warning(`${(error as any)?.message ?? error}`)
  }
}

// Main
if (!stateHelper.IsPost) {
  run()
}
// Post
else {
  cleanup()
}
